This book made me hungry but I could not eat it. So that was sad. Also if you forgot what you were doing last week, then you will feel real dumb in this Japanese restaurant, because there are plenty of characters in this book who recall menu details, names, what they had for tea, every ingredient they used for a meal, from half a century or more.
One issue I had was that this detective agency has a TERRIBLE business plan. They tell their clients to pay what they want. They do not advertise. They give away free meals. They do not have proper signs nor a website. They accept vague quests with little chance of success, wasting many potentially profitable working hours.
Na-uh.
